Nodit will apply a new Data API data retention policy for all Testnets starting Tuesday, November 25, 2025, after 05:00 UTC (14:00 KST).

This change introduces a 90-day data retention limit for all Testnets chains. After the update, only data from the most recent 90 days will be available through the Data API.

This policy does not apply to chains for which Nodit currently provides only a Testnet (without Mainnet support). For these networks, all data will remain accessible without the 90-day limit.

Affected Networks

The new 90-day retention policy applies to the following chains:

ProtocolNetworkRetention Policy
ArbitrumSepolia90 days
BaseSepolia90 days
EthereumSepolia, Hoodi90 days
GiwaSepoliaNo Limit
KaiaKairos90 days
OptimismSepolia90 days
PolygonAmoy90 days

This policy will also apply to any future Testnets added to the Data API, except for those that do not have a corresponding Mainnet supported by Nodit.

What’s Changing

  • All Testnet responses from the Data API will return data from the <span style={{ color: "#d9534f", fontWeight: "bold" }}>past 90 days only (excluding testnet-only chains).

  • When requesting snapshot data (e.g., a block or transaction hash) older than 90 days, the following error message will be returned:

    {
  "code": "RESOURCE_NOT_FOUND",
  "message": "Resource not found: { RESOURCE_NAME = RESOURCE_VALUE }. Testnet only retains data from the past 3 months. To access older data, please use an RPC API."
}

  • For state-based resources such as accounts, token holders, and smart contracts, accumulated states will continue to be returned as before.

  • For multi-record queries, only data within the 90-day retention window will be included.

  • When using fromDate or toDate parameters that extend beyond the 90-day range, the response will contain no data for those periods, without triggering an error.

APIs Directly Affected

The following APIs will be directly affected ⏤ will throw 404 Not Found error for hash or id before 90 days ⏤ by this policy change(for each networks):

Other Data APIs will also no longer return data older than 90 days after this change.

This adjustment is part of Nodit’s ongoing effort to optimize resources for less frequently accessed datasets, allowing us to enhance performance and expand support for additional chains and features.

We appreciate your understanding as we implement this change to deliver a more efficient and scalable service environment.
